Description Raghavendra G 2018-01-23 06:30:36 UTC

Description of problem:
Recently (in rhgs-3.4.0 cycle) to fix ping-timeout issue we introduced a thread to process all requests inbound to Glusterfs program[1]. With bricks multiplexed and all bricks served as part of same program, huge traffic of requests can be expected. This thread is likely to be a bottleneck. However, there is some evidence that this thread can be a bottleneck (though with NVMe backend)[2]

Sunil - We need to have a release candidate tag for this considering the fix was reverted due to the revert of the ping timer expiry patches.

Comment 10 Milind Changire 2018-11-20 09:32:58 UTC

This issue does not apply to RHGS 3.4.0 since the patches inherited from the rebase to 3.12.2 upstream have been reverted in RHGS 3.4.0.
Closing as NOTABUG.
